Raman spectroscopy has advanced considerably in the last several years due to rapid developments in instrumentation and the availability of theoretical methods for accurate calculation of Raman spectra, thus enormously facilitating the interpretation of Raman data. This review is restricted to cover papers mainly published in the Journal of Raman Spectroscopy, which serve to give a fast overview of recent advances in this research field as well as to provide readers of this journal a quick introduction to the various subfields of Raman spectroscopy. It also reflects the current research interests of the Raman community. Similar reviews of highly active areas of Raman spectroscopy will appear in future issues of this journal.

“…In these processes energy is parametrically transferred between Stokes and anti-Stokes fields via interaction with vibrational modes of the material in the presence of a strong pump wave. It was discovered by Maker and Terhune in the early days of nonlinear optical research (Maker and Terhune 1965), it has found numerous applications in spectroscopy and substance identification (Vogt 1982;Zheltikov and Radi 2005) and continues as an active field of applied research (Beadie et al 2005;Djaker et al 2004). The present work shows that squeezing is greater in CAHRS than the corresponding squeezing in CARS.…”

The Squeezing and sub-poissonian photon statistics of an optical field are a purely quantum mechanical phenomenon and has been accepted as means of achieving noise below the quantum shot-noise limit. The effect of higher-order squeezing and sub-poissonian nature of an optical field in coherent anti-Stokes Raman scattering (CARS) and coherent anti-Stokes hyper Raman scattering (CAHRS) are investigated under short-time approximation. The coupled Heisenberg equations of motion involving real and imaginary parts of the quadrature operators are established and solved under short-time scale. The dependence of squeezing on the number of photons is also investigated. It is also shown that higher-order squeezing allows a much larger fractional noise reduction than lower-order squeezing. The occurrence of amplitude squeezing effects of the radiation field in the fundamental mode is investigated in both the processes. The present work shows that squeezing is greater in CAH-RS than the corresponding squeezing in CARS. It is also shown that squeezing is greater in stimulated process than corresponding squeezing in spontaneous interaction. The conditions for obtaining maximum and minimum squeezing are obtained. The photon statistics of the pump mode in the processes has also been investigated and found to be sub-poissonian in nature.

“…Besides these two linear Raman spectroscopic techniques, inelastic, non-linear scatterings in which the vibrational degrees of freedom in molecular systems are measured using Raman methodologies have been of particular interest. 4 Since the first observation of coherent Raman scattering via the mixing of four electromagnetic waves in 1965, 5 several other non-linear Raman phenomena have been observed and developed as spectroscopic methods. These non-linear Raman spectroscopies, especially those involving the four-wave mixing (FWM) phenomena, have been widely used for numerous applications in condensed and gas-phase studies, and, very recently, in femtochemistry.…”
